Ok...I am able to accept payments now but once a user has been registered, it does not show up in the Registration Records on the backend. It does however show up when I export to a CSV.
I am using Authorize.net. The payments are working and I am being charged for the test transactions. When the transaction is completed however, I go into the backend and there are no registrations showing under the Registration Records. I also go and look at the event capacity and number of registered users. The capacity is correct but the number of registered users is 0.
